Development of a printed paperbased origami electrochemical sensor for the detection of heavy metals in water

Author: Madzivhandila, Phophi ; Smith, Suzanne ; Ntuli, Letta ; Land, Kevin J Date: Oct 2018 This paper presents a printed paper-based origami electrochemical sensor for the detection of heavy metals in water. Heavy metal contamination in water has significant health risks and environmental complications. The detection is typically ... Read more
The effect of g-C3N4 materials on Pb(II) and Cd(II) detection using disposable screen-printed sensors

Author: Zheng, Haitao ; Ntuli, Letta ; Mbanjwa, Mesuli ; Palaniyandy, Nithyadharseni ; Smith, Suzanne ; Modibedi, Remegia M ; Land, Kevin J ; Mathe, Mahlanyane K Date: Dec 2018 The disposable electrochemical sensors were designed and fabricated onto a photo paper substrate in-house. We report a first case use of g-C3N4, which is an emerging material as the most stable carbon-like polymer, explored for application ... Read more
Printed paper–based electrochemical sensors for low-cost point-of-need applications

Author: Smith, Suzanne ; Madzivhandila, Phophi ; Ntuli, Letta ; Bezuidenhout, Petrone H ; Zheng, Haitao ; Land, Kevin J Date: Feb 2019 Paper-based microfluidics is a rapidly developing field with applications for point-of-care disease and environmental diagnostics. In parallel, printed electronics has grown swiftly, particularly for wearable technologies. By combining these ... Read more
